Fascinating article, both for the actual benches, as well as the explanation of some of the hardware and technology underneath. Also included in a dissection of the JMicron controller found in many other SSD's, and the performance anomalies they seem to be incurring.
Intel wanted to represent its SSD lifespan as a function of the amount of data written per day, so Intel met with a number of OEMs and collectively they came up with a target figure: 20GB per day. OEMs wanted assurances that a user could write 20GB of data per day to these drives and still have them last, guaranteed, for five years. Intel had no problems with that.Intel went one step further and delivered 5x what the OEMs requested. Thus Intel will guarantee that you can write 100GB of data to one of its MLC SSDs every day, for the next five years, and your data will remain intact.
The longevity issue has always been a vague one where SSD's have been concerned. Quite refreshing to see a guarantee given in plain(er) terms.
